Energizer XP1000
My usage pattern (heavy mobile browsing, moderate SMS, and some calls) coupled with Smart’s poor 3G network coverage results in dismal battery performance of my iPhone 4S. Despite my best efforts, standby is at only 20 hours with usage of around 4 hours and that already includes my sleeping time. Fully charged in the morning, I get up to12-14 hours of standby before I need to recharge. Usually, I’m back home by then. But that means I have a problem when I’m away for more than half the day.
My solution is the Energizer XP1000. It is a small (about the size of 1/3 a deck of cards) and light emergency charger and backup battery. It has a “universal” charging cable that allows you to charge the XP1000 via a USB port and charge different devices by attaching different tips or connectors for different standards/devices. The package includes tips for mini-USB, micro-USB, iPhone/iPod, and Nokia.
The XP1000 specifications claims it stores a charge for a year, can be recharged up to 500 times, and is rated at 1000mAh. It charges my iPhone 4S from almost empty to just over 50% in around 2 hours. Not bad. That should give me an extra 6-7 hours of standby and a corresponding amount of usage. My only quibble is that the universal charging cable makes carrying the XP1000 around in your pocket a bit less convenient. But it’s not a problem if you have a gadget bag.
